Anti-vibration foot seat with fixing sliding sleeve

Abstract

Disclosed is an anti-vibration foot seat with a fixing sliding sleeve. The anti-vibration foot seat comprises an upper base, a lower base, a ball and the sliding sleeve, wherein the ball is arranged in arc-shaped grooves formed in the upper base and the lower base and the arc-shaped grooves are in point contact with the ball, and the anti-vibration effect is achieved. When the foot seat is installed under equipment, by means of the sliding sleeve, the upper base, the lower base and the ball are in an aligned and centered state. Therefore, the mounting is easier, the foot seat can be prevented from possibly shifting or inclining during mounting, and the anti-vibration effect of the foot seat is optimized.

Description

Technical field [0001] The present invention relates to an anti-vibration foot base, in particular to an anti-vibration foot base that is easy to install and avoids displacement and skew that may occur during installation. Background technique [0002] In today's technologically advanced society, there are many sophisticated equipment, such as semiconductor process equipment, to common equipment in ordinary homes. And because it is a sophisticated device that requires a certain degree of protection, anti-vibration becomes one of the most important protection measures. [0003] There are many sources of equipment vibration, including: the vibration of the equipment itself, environmental impact, man-made vibration, natural vibration (earthquake), etc. The general anti-vibration is solved by the contact surface between the equipment and the ground. [0004] The prior art of Taiwan's new manual 106223 "Anti-seismic foot stand for audio visual equipment" discloses a kind of anti-seismic...

AI Technical Summary

Problems solved by technology

[0005] However, there are several deficiencies in the prior art. First: Since the upper seat 900 and the lower seat 910 are only connected by the point contact of the steel ball 930, when the anti-seismic feet are installed, the upper seat 900 and the lower seat 910 are easy to shift and cannot be fixed. , it is easy to cause skew during installation, and it is very troublesome to install the anti-seismic feet on the four corners of the equipment; second: when the installation is completed in the previous technology, it is difficult to judge and check whether the steel ball 930 is in the center position; third: The curvature of the groove 920 is only slightly larger than that of the steel ball 930. When a shock with a large amplitude like an earthquake occurs, it cannot effectively prevent the shock. Fourth: When the anti-seismic feet are installed on the four corners of the equipment, the height will often be caused by a slight error on the ground. Different, in the case of no height adjustment function, it will also cause uneven force on the anti-seismic feet and affect the shock-absorbing function
